I've been Using an Asus A7n8x-e Deluxe motherboard for about 8+ years without any serious problems until this past week.
my setup is:
Motherboard: ASUS A7N8X-e deluxe bios 1013
Videocard: ATI Radeon X850 DDR
Processor: AMD Athlon XP 2700+ Thoroughbred 2.167GHz Socket A Processor Model AXDA2700BOX (BARTON)
Ram: 3gb Corsair XMS PC3200 DDR400mhz
Last Saturday morning I went to take out an ATI Tv tuner (theater 550) pci card and then it would not turn on.
Here is the sequence of events are that may have led to the problem:
Friday night I was editing video in Windows Movie Maker which I am not that skilled with, and noticed that it was crashing and hanging a lot. It looked like it was doing a number on the cpu, but I shut it down like I normally do at night (checked some email etc, that shut it off).
Saturday morning I turn on computer and check email. I shut down the computer and decide to take out ATI tv tuner card which I am not using so that I can go into the BIOS and change the AGP setting to 256mb for the ATI x850 256mb agp card (thinking that this might help with the video-editing, I could not get the tuner card to work properly unless I put AGP on 64mb.) I take out the tv-tuner card, and go to restart computer and it won't start.
I take it apart, run tests (reseating ram) to determine the problem and all I could get were the (cpu, powersupply, graphic card) fans to spin for 1 second. I tried alternate Power Supply and it worked. I went out and bought new 400 watt PS and it still worked. I went into BIOS and changed the setting for the ram to 2-3-3-6 and let it run for atleast a half hour. By then it was late, and I put my computer back into my computer desk, hooked up all the USB related stuff (a cordless mouse), speakers, mic, keyboard etc. and it would not start again. (I was steaming mad, but went to sleep.)
Next day, I look at it again.
It would just spin the fans for 1 second.
I tried with NO RAM installed, 1 stick of Ram installed.
I tried reseting the cmos. I tried with no hard-drives. No drives.
I tried with 4 different Power supplies. I tried everything.
No matter what I did, I would see that GREEN LED LIGHT, LIGHT UP,
and then I'd press the power button and the fans spin for 1 second and then nothing!
The night before when I was in the BIOS I checked the CPU temp and it was fine.
I honestly do not know what else to look for... I was talking to some techie people that it could be a CMOS related problem...
